Australia's Great Barrier Reef has suffered its most widespread coral bleaching on record. It is a big threat posed by climate change to the world's largest living organism.

Context

Australia's Great Barrier Reef has suffered its most widespread coral bleaching on record. It is a big threat posed by climate change to the world's largest living organism.

Background:

  • Bleaching was first seen on the reef in 1998 -- at the time, the hottest year on record -- but as temperature records continue to tumble its frequency has increased, giving coral less time to recover.
  • Back-to-back bleaching events in 2016 and 2017 prompted the government agency overseeing the reef to downgrade its long-term outlook to 'very poor'.
  • Aerial analysis conducted by Terry Hughes, director of the ARC Center of Excellence for Coral Reef Studies at James Cook University, and others from the Great Barrier Reef Marine Park Authority, found that coastal reefs along the entire length of the iconic reef -- a stretch of about 1,500 miles (2,300 kilometers) from the Torres Strait in the north, right down to the reef's southern boundary -- have been severely bleached.
  • This marks the third mass bleaching eventon the reef in just the last five years and scientists say that the rapid warming of the planet due to human emissions of heat-trapping gases are to blame.
